Started at the Home Depot today...$350 on materials for my son's mini half. Actually it's for me the old fart who wants to get back into it. I've been ripsticking with my 6 year old and it's got me ready for more action.

My first skate was a 2X4 with metal roller skate wheels. We invented the boards and the half pipe.

Thanks for the plans! I have downscaled to all 2X4's and 3/8 inch ply. I'll see how it goes and post a pic soon!
